Super poor service and no commitment or accountability

Extremely disappointing experience! This morning our adsl line has no not work. Call is logged and a technician called at 8:30. Inform technician that I am not home ask if he can come at 17:30, he agrees at 17:00 I call him only to be told he knocked off. He can't come as he is done working. Then I asked if this was handed over to another team he said yes the emergency/after hours team will assist. Note is made to job card. I started to discuss this with the social platform - no support just a sorry this is escalated. Despite agreeing on a specific timeline, the team failed to meet the committed deadline. To make matters worse, the staff falsely claimed that I didn't answer their call, when in fact we spoke 2x for over a minute and twenty seconds. When I brought this to social teams attention, they simply dismissed my concerns on social media with a flippant 'sorry' it has been escalated. This disgrace and Unacceptable service and blatant disregard for customer time and the service is just I don't care
